CHARACTERIZATION OF Colletotrichum truncation ISOLATES TRANSMITTED FORLIMA BEAN PLANT THROUGH SEEDS

摘要

In the Northeast of Brazil, lima bean {Phaseolus lunatus L.) is an important source of food and income for the population of this region. However, the occurrence of pests and diseases especially anthracnose (Carvalho et al., 2015) and the use of low quality seeds has contributed to the reduction of the crop productivity. The objective of this study was to evaluate the transmissibility of the pathogen via the seed and to characterize the isolates in relation to mycelial growth (mean colony diameter and mycelial growth rate index) and sporulation (colony conidia cm-2).
